Document.referrer
Returns the URI of the page that linked to this page.
Syntax
JavaScript
Copy Code
<var>string</var> = document.referrer;
Notes
The value is an empty string if the user navigated to the page directly (not through a link, but, for example, via a bookmark). Since this property returns only a string, it does not give you DOM access to the referring page.
